Background: Lenalidomide, a synthetic immunomodulatory drug, has a wide range of features including anti-angiogenic and anti-proliferative properties. To date, researchers have shown that lenalidomide is capable of ameliorating the immune system factors and antitumor responses. Most researchers have reported that lenalidomide enhances the immune response in certain cancer patients through sever...

natural killer (nk) cells are a subset of lymphocytes which play a crucial role in early innate immune response against infection and tumor transformation. furthermore, they secrete interferon-γ (ifn-γ) and tumor necrosis factor (tnf) prompting adaptive immu-nity. nk cells distinguish the unhealthy cells from the healthy ones through an array of cell-surface receptors. human nk cells use inhibi...

allergic rhinitis  (ar) is  an  inflammatory  disorder  of  the  nasal  mucosa  with  high morbidity and prevalence. natural killer (nk) cells might have a role in ar. we aimed to evaluate the changes of the markers and receptors on nk cells in ar patients compared to the non-atopic controls. flow  cytometric  analysis was  used  with  double  staining  of  the  peripheral  blood mononuclear ce...

Let m,n,s,k be four integers such that 3?s?n, 3?k?m and ms=nk. Set d=gcd?(s,k). In this paper we show how one can construct a Heffter array H(m,n;s,k) starting from square H(nk/d;d) whose elements belong to d consecutive diagonals. As an example of application method, prove there exists integer in each the following cases: (i) d?0(mod4); (ii) 5?d?1(mod4) nk?3(mod4); (iii) d?2(mod4) nk?0(mod4); ...

materials and methods in the present study, a potent nk-producing strain was isolated from cow milk and identified. to enhance the yield of nk, effect of various parameters such as ph, temperature, carbon source, nitrogen source and inoculum size were optimized. strain improvement of p. aeruginosa cmss was done by random uv-mutagenesis. nattokinase was partially purified and the activity was de...

Exosomes are released by various cells, including natural killer (NK) cells and transport signaling molecules for the intercellular communication. Hepatocellular carcinoma (HCC), also known as primary liver cancer, is often inoperable difficult to accurate diagnosis. Notably, prognosis underlying mechanisms of HCC not fully understood. Exosomes-derived NK (NK-exos) express unique cytotoxic prot...
